20090052448 | METHODS AND SYSTEMS TO STORE STATE USED TO FORWARD MULTICAST TRAFFIC - Methods and systems are described to store state used to forward multicast traffic. The system includes a receiving module to receive request to add a first node to a membership tree. The membership tree includes a first plurality of nodes associated with a multicast group. The system further includes a processing module to identify a second node in the first plurality of nodes and to communicate a node identifier that identifies the first node over a network to the second node. The node identifier is to be stored at the second node to add the first node to the membership tree. The node identifier is further to be stored in the membership tree exclusively at the second node to enable the second node to forward the multicast traffic to the first node. | 02-26-2009 |
20090052449 | MULTICAST WITH ADAPTIVE DUAL-STATE - A method and system are described to multicast with an adaptive dual state. The system receives multicast traffic over a membership tree including a first plurality of nodes connected in a first topology destined for a plurality of multicast members of a first multicast group. Next, the system determines a rate of multicast traffic that exceeds a predetermined threshold based on the receiving the multicast traffic. Next, the system generates a dissemination tree including a second plurality of nodes connected in a second topology to reduce a number of hops to communicate the multicast traffic to the plurality of multicast members of the first multicast group. Finally, the system forwards the multicast traffic to the plurality of multicast members of the first multicast group over the dissemination tree. | 02-26-2009 |

20090265421 | Internet measurement system application programming interface - Systems, application programming interfaces, and other embodiments associated with internet measurements are described. Example systems and methods facilitate requesting that a control server acquire internet measurements from a set of distributed measurement points. One example application programming interface (API) includes a list request interface to provide a list request to a control server. The list request may request a list of measurement points from the control server. The example API may also include a list receipt interface to receive a list response from the control server. The list response may contain information concerning measurement points. The API may enable a user to perform a complex series of internet measurements by giving the user access to standardized function calls for accessing a distributed internet measurement system. | 10-22-2009 |
20100023512 | Methods and Systems for Content Access and Distribution - Distribution of content between publishers and consumers is accomplished using an overlay network that may make use of XML language to facilitate content identification. The overlay network includes a plurality of routers that may be in communication with each other and the publishers and consumers on the Internet. Content and queries are identified by content descriptors that are routed from the originator to a nearest router in the overlay network. The nearest router, for each unique content descriptor, generates a hash identification of the content descriptor which is used by remaining routers in the overlay network to provide the appropriate functions with respect to the content descriptor. In particular, this allows all routers in the overlay network except the nearest router to properly route content without processing every content descriptor. | 01-28-2010 |
20110029596 | Anycast Transport Protocol for Content Distribution Networks - A cache server for providing content includes a processor configured to receive a first datagram from a client system sent to an anycast address, send a response datagram to the client system in response to the first datagram, receive a request datagram from the client system sent to the anycast address, and send a batch of content datagrams to the client system. The first datagram includes a universal resource locator corresponding to the content. The response datagram includes a content identifier for the content. The request datagram includes the content identifier, an offset, and a bandwidth indicator. The batch of content datagrams includes a portion of the content starting at the offset. | 02-03-2011 |
20110153941 | Multi-Autonomous System Anycast Content Delivery Network - A content delivery network includes first and second sets of cache servers, a domain name server, and an anycast island controller. The first set of cache servers is hosted by a first autonomous system and the second set of cache servers is hosted by a second autonomous system. The cache servers are configured to respond to an anycast address for the content delivery network, to receive a request for content from a client system, and provide the content to the client system. The first and second autonomous systems are configured to balance the load across the first and second sets of cache servers, respectively. The domain name server is configured to receive a request from a requestor for a cache server address, and provide the anycast address to the requestor in response to the request. The anycast island controller is configured to receive load information from each of the cache servers, determine an amount of requests to transfer from the first autonomous system to the second autonomous system; send an instruction to the first autonomous system to transfer the amount of requests to the second autonomous system. | 06-23-2011 |
20110162217 | Compact knife holder - The invention proposes a wall-mounted knife holder, which comprises a pack of several plates separated by narrow and thin strips as spacers. The space between two successive strips forms a channel for the knife blade. The rows of channels in any two adjacent pairs of plates crisscross each other but the plates are stacked, the crisscrossed channels do not intersect, and the knives using these channels do not touch each other. At the same time, knives in all the rows utilize the same space on a wall surface, which makes the knife holder compact. The holder is attached to a wall so that the channels from both sides are at an angle that ensures that the force of gravity holds the knives in the channels. The front plate of the holder can be made from a decorative material and adorned with beatifying design. | 07-07-2011 |

20120255699 | EXOTHERMIC WELDING MOLD WITH FILTER - An exothermal weld mold includes a mold section with an integral cover portion, made as part of a single piece of material with the rest of the mold section. The mold section may be a mold half of a vertically split mold, or may constitute most of a half of the mold. The cover portion may be part of an integral cover that covers substantially all of a reaction chamber or crucible of the mold. The cover may have one or more vent holes, in the top and/or side of the mold. The cover may have a baffled passage for expansion of gases produced by reaction of the weld material, before the gases are expelled from the mold at an opening in the top or side of the mold. The passage may be a serpentine passage. A filter may be placed in the passage. | 10-11-2012 |

20140164566 | Methods and systems for content access and distribution - A method for disseminating content over an overlay network having a plurality of routers in communication with providers and consumers of content is disclosed. A router in the overlay network receives a content descriptor corresponding to a query for content from a node, and generates a subscriber interface list based on the query for the content. The subscriber interface list is transmitted to a plurality of subsequent routers in the overlay network, wherein a content identified by the subsequent routers that correspond to the query will be routed to the router based on the subscriber interface list. The router receives first and second documents corresponding to the query for the content from the node. If the second document is the duplicate, the router deletes the second document and transmits the first document to the node or if not the router transmits both the first and second documents to the node. | 06-12-2014 |
